The validity data of the evaluation instruments collected included the material, construction, and language domains. The percentage of validity level is done by dividing the number of valid or invalid instruments by the number of validity criteria then multiplied by one hundred. Based on the research that has been done it can be known, that the evaluation instrument about writing a trial report has not fully fulfilled the validity element.
